Pie Chart

This documentation pertains to the unsupported version of NeoDash, as part of Neo4j Labs. For users of the supported NeoDash offering, refer to NeoDash commercial.

A pie chart will draw categories and values in a circular disc layout. The pie chart will require you to choose the following selections:

Category: a text field. These will be the labels on the pie slices.
Value: a numeric field. This will be the size of the slices.

The pie chart can be additionally be customized to become a donut chart, show categories as a legend, and to show the percentage of the total value of the pie. See Advanced Settings for more information.

Examples

Basic Pie Chart

Match (p:Person)-[e]->(m:Movie)
RETURN m.title as Title, COUNT(p) as People
LIMIT 8

Donut Chart

MATCH (p:Person)-[e]->(m:Movie)
WHERE m.title = "Cloud Atlas"
WITH TYPE(e) as Role
RETURN Role, COUNT(Role) as Count
